Cards in Inverters
Information on installing option cards in the inverters and for connecting data communica-
tion cables can be found in the installation instructions.
Fronius developed Solar Net to make these system add-ons flexible and capable of being
used in a wide variety of different applications. Fronius Solar Net is a data network that
enables several inverters to be linked to the system add-ons.
Fronius Solar Net is a bus system with ring topology. Just one suitable cable is enough
to provide communication between one or more inverter connected to Fronius Solar Net
and a system add-on.
Different system add-ons are automatically recognized by Fronius Solar Net.
In order to distinguish between several identical system add-ons, each one must be as-
signed a unique number.
In order to clearly define each inverter in Fronius Solar Net, each inverter must also be
assigned an individual number.
You can assign individual numbers as per the "SETUP Menu" section in this manual.
More detailed information on individual system upgrades can be found in the relevant op-
erating instructions or on the internet at http://www.fronius.com
